What is going on?? Help!!

Late post but what the hell. It was simply calcium deficient. Rust spots on fan leaves usually starting at the middle of plant

I just reread it too and noticed that they're using Ph Perfect in soil. That says all i need to hear. I tried that in FFOF too...Once...it causes all kinds of craziness. I am using it in Pro-Mix now and its the shanizzle for the moment anyhow. Ive always heard to treat it like youre running hydro. I got a deal and tried it. Better doing organics in soil until you get used to measuring and phing your salt nutes IME. I have struggled with salts in soil for these autos. Its so easy to miss your mark and fry or stunt them. Im a stoner. I forget shit lol....oh and i tend to ramble too
